Hello

I have an issue with my Philips Saeco Intuita HD8750, the coffee is not strong enough.

The grinder runs 8 seconds and the quantity of ground coffee is low. I check the grinder, ceramic discs, all function but I can't modify the running time for grinder.
Service manual?
Factory reset procedure?
PIC -dump ?
Any help is welcome.

Thank you
